First, the DC would not know the number of users. Second, 1.2PB is not that much. It can fit into a single rack, of which a DC may have hundreds.

My guess would be that whoever is suspecting DC personnel does not understand the technology involved. Same as you.

Under US Pressure, PayPal Stops Working With Mega 135

Posted by Soulskill
from the you-wouldn't-download-a-car dept.
New submitter seoras sends news that PayPal is now refusing to handle payments for Mega, Kim Dotcom's cloud storage service. A report (PDF) issued in September of last year claimed Mega and other "cyberlocker" sites made a great deal of illicit money off piracy. Mega disputes this, of course, and says the report caused U.S. Senator Patrick Leahy to pressure credit card companies to stop working with Mega. Those companies then pressured PayPal to stop as well. The hosting company claims, "MEGA provided extensive statistics and other evidence showing that MEGA’s business is legitimate and legally compliant. After discussions that appeared to satisfy PayPal’s queries, MEGA authorised PayPal to share that material with Visa and MasterCard. Eventually PayPal made a non-negotiable decision to immediately terminate services to MEGA."

We Stopped At Two Nuclear Bombs; We Can Stop At Two Degrees. 340

Lasrick writes Dawn Stover writes in the Bulletin of the Atomic Scientists that climate change is irreversible but not unstoppable. She describes the changes that are happening already and also those likely to happen, and compares what is coming to the climate of the Pliocene: 'Even if countries reduce emissions enough to keep temperatures from rising much above the internationally agreed-upon "danger" threshold of 2 degrees Celsius (which seems increasingly unlikely), we can still look forward to conditions similar to those of the mid-Pliocene epoch of 3 million years ago. At that time, the continents were in much the same positions that they are today, carbon dioxide levels ranged between 350 and 400 ppm, the global average temperature was 2 to 3 degrees Celsius higher than it is today (but up to 20 degrees higher than today at the northernmost latitudes), the global sea level was about 25 meters higher, and most of today's North American forests were grasslands and savanna.' Stover agrees with two scientists published in Nature Geoscience that 'Future warming is therefore driven by socio-economic inertia," and points the way toward changing a Pliocene future.

Ask Slashdot: Terminally Ill - What Wisdom Should I Pass On To My Geek Daughter? 698

Posted by Soulskill
from the f*#&-cancer dept.
An anonymous reader writes: I am a scientist and educator who has been enjoying and learning from Slashdot since the late 90s. Now I come to you, my geek brothers and sisters, for help. I've been diagnosed with Stage 4 pancreatic cancer, which you will remember is what took Steve Jobs and Randy Pausch from us. My condition is incurable. Palliative chemotherapy may delay the inevitable, but a realistic assessment suggests that I have anywhere from two to six months of "quality" time left, and likely not more than a year in total.

I am slowly coming to terms with my imminent death, but what bothers me most is that I will be leaving my wife alone, and that my daughter will have to grow up without her father. She is in sixth grade, has an inquisitive and sharp mind, and is interested in science and music. She seems well on the path to becoming a "girl geek" like her mother, an outcome I'd welcome.

Since I will not be around for all of the big events in her life, I am going to create a set of video messages for her that she can watch at those important times or just when she's having a bad day. I would like to do this before my condition progresses to the point that I am visibly ill, so time is short.

In the videos I will make clear how much I treasure the time we've spent together and the wonderful qualities I see in her. What other suggestions do you have? What did you need to hear at the different stages of your life? What wisdom would have been most helpful to you? At what times did you especially need the advice of a parent? And especially for my geek sisters, how can I help her navigate the unique issues faced by girls and women in today's world?

Please note that I'm posting anonymously because I don't want this to be about me. I'd prefer that the focus be on my daughter and how I can best help her. Thank you so much for your help.

Yeah. If only there was an easy to use end2end encrypted mobile phone application for voice calls that Moxie had been involved in creating.

Indeed. Moxie is quite good. But he is wrong here: GPG/PGP is about as simple as you can be and still offer strong security. It can be put into wrappers for a little decrease in security and some increase to usability, but that is it. In security, you cannot make a hard task simple. That is not possible without massively decreasing security.The same thing happens when you say learning to read and write is too hard. Sure, speech recognition and synthesis does allow some help, but you will never be able to use a pen or a keyboard, and it does not help you at all with deciding what to write and what the meaning of some text is. This is a hard task as well, and cannot be automatized away.

The fact of the matter is that it takes real effort to learn to use encryption securely and that nothing can be done abut that.
